I need to have an oral maintenance abx for a few weeks until I get my next cycle of Aztreanam. I just finished up 3 weeks of IV's and inhaled Aztreanam. Now I need something to cover me for 4 weeks. My new doc has recommended Cipro 500 mg 2x/day by itself. Do any of you who culture PA use this med BY ITSELF as a maintenance. It will just be for the four weeks and I will go on something different after that. I have heard it is not good to use a PA sensitive drug by itself; but, for maintenance over a month....I am just wondering.
